Romania, Panama cutting back on spam

Romania and Panama, two of the world’s notable sources of spam, now have fewer computers producing it, according to security vendor Cloudmark.

The U.S. remains first in having the most systems blocked by IP address for sending junk mail, though by the percentage of its total IP addresses, it ranks fairly low.

Cloudmark, which specializes in providing antispam products to ISPs, said it is blocking 13 percent fewer IP addresses worldwide for sending spam, with notable improvements in a few small countries, according to its first quarterly report for this year. The report covered IPv4 addresses, which are used for the vast majority of Internet traffic.
